<p>The present invention relates to the use of a combination of additives comprising at least two of the following compounds:
- an antioxidant (A) according to formula (I):
wherein R 1 , R 2 , R 3 , R 4 and R 5 independently are H, or non-substituted or substituted aliphatic or aromatic hydrocarbyl radicals which may comprise heteroatoms,
- an antioxidant (B) according to formula (II):
wherein
o R 6 , R 7 and R 8 independently are non-substituted or substituted aliphatic or aromatic hydrocarbyl radicals which may comprise OH-groups;
—‹ X 1 , X 2 , and X 3 independently are H or OH, with the provisio that at least one of X 1 , X 2 and X 3 is OH; and
o the entire molecule does not comprise an ester group;
and,
- carbon black;
for reducing taste and/or odour in a polyolefin composition.</p> |
